Description

Beschreibung description
Anzeigeeinrichtung Die Erfindung bezieht sich auf eine Anzeigeeinrichtung mit einer kreisbogenförmigen Skala, an der entlang das freie Ende eines von einem Meßwerk um eine Zeigerachse drehbar antreibbaren Zeigers bewegbar ist. Bei derartigen Anzeigeeinrichtungen sind auf Leiterplatten montierte, druck- oder lötkontaktierte Messwerke mit inte¬ grierten elektromagnetischen Antriebssystemen bekannt, die einen Permanentmagneten, gewickelte Spulen und einen mehr oder weniger komplexen Eisenkreis beinhalten. Die dabei erzeugte Drehbewegung wird über ein ein- oder mehrstufiges Getriebe in eine Bewegung der Zeigerachse umgesetzt. Dies führt zu hohen Herstellkosten. Mittels einer Korrekturkurve für die Ansteuerung muss eine Gleichförmigkeit der Zeigerbewegung erzeugt werden. Aufgabe der Erfindung ist es daher, eine Anzeigeeinrichtung der eingangs genannten Art zu schaffen, die einen kostengünstigen, einfachen Aufbau mit wenigen Bauteilen aufweist und eine gleichförmige Zeigerbewegung ermöglicht. Diese Aufgabe wird erfindungsgemäß in einer ersten Ausführung dadurch gelöst, dass auf einer die Zeigerachse direkt oder indirekt antreibenden Achse ein drehbar gelagertes Zahnrad drehfest angeordnet ist, in dessen Zähne die Verzahnung eines einen größeren Durchmesser als das Zahnrad aufweisenden Tau- melzahnkranzes teilweise eingreift, der um die Achse des Zahnrads taumelbar gelagert ist, von an seinem Umfang verteilten Fe¬ derkräften in Eingriffsrichtung der Verzahnung des Taumel¬ zahnkranzes in die Zähne des Zahnrads beaufschlagt und mit einem in die Umlaufrichtung des Taumelzahnkranzes sich erstreckenden ferromagnetischen Ring fest verbunden ist, mit mindestens zwei Polschuhen, die durch unabhängig voneinander bestrombare Spulen hindurch zur äußeren umlaufenden Mantelfläche des ferromag- netischen Rings ragen und mit radialem Spiel zum ferromagne- tischen Ring an dessen Umfang verteilt angeordnet sind. The invention relates to a display device with a circular arc-shaped scale along which the free end of a pointer rotatably driven by a movement about a pointer axis can be moved. In such display devices mounted on printed circuit boards, pressure or solder-contacted measuring units with inte ¬ grated electromagnetic drive systems are known, which include a permanent magnet, wound coils and a more or less complex iron circle. The rotational movement generated in this case is converted via a single or multi-stage gear in a movement of the pointer axis. This leads to high production costs. By means of a correction curve for the control, a uniformity of the pointer movement must be generated. The object of the invention is therefore to provide a display device of the type mentioned, which has a low-cost, simple construction with few components and allows a uniform pointer movement. This object is achieved according to the invention in a first embodiment in that a rotatably mounted toothed wheel is rotatably mounted on an axis which directly or indirectly drives the axis, in whose teeth the toothing of a larger diameter than the toothed gear partially engages the toothed ring the axis of the gear is mounted wobble, distributed from its circumference Fe ¬ derkräften in the direction of engagement of the teeth of the swash ¬ ring gear in the teeth of the gear and is firmly connected to a in the direction of rotation of the wobble ring extending ferromagnetic ring, with at least two pole pieces , which are fed through coils which can be energized independently of one another, to the outer circumferential surface of the ferromagnetic material. projecting net rings and are arranged distributed with radial play to the ferromagnetic ring on its circumference.
Die Aufgabe wird erfindungsgemäß in einer zweiten Ausführung dadurch gelöst, dass auf einer die Zeigerachse direkt oder indirekt antreibenden Achse ein drehbar gelagerter Innenzahn¬ kranz drehfest angeordnet ist, in dessen Zähne die Verzahnung eines einen kleineren Durchmesser als der Innenzahnkranz auf¬ weisenden Taumelaußenzahnkranzes teilweise eingreift, der um die Achse des Innenzahnkranzes taumelbar gelagert ist, von an seinem Umfang verteilten Federkräften in Eingriffsrichtung der Ver¬ zahnung des Taumelaußenzahnkranzes in die Zähne des Innen¬ zahnkranzes beaufschlagt und mit einem in der Umlaufrichtung des Taumelaußenzahnkranzes sich erstreckenden ferromagnetischen Ring fest verbunden ist, mit mindestens zwei Polschuhen, die durch unabhängig voneinander bestrombare Spulen hindurch zur inneren umlaufenden Mantelfläche des ferromagnetischen Rings ragen und mit radialem Spiel zum Ring an dessen Umfang verteilt angeordnet sind. The object is inventively achieved in a second embodiment in that on a pointer shaft directly or indirectly driving axis, a rotatably mounted inner teeth ¬ wreath, is arranged in a rotationally fixed partially engages in the teeth of the toothing of a smaller diameter than the inner ring gear ¬ facing swash external gear, which is mounted to be wobble about the axis of the internal gear, is acted upon by circumferentially distributed spring forces in the direction of engagement of the Ver ¬ toothing of Taumelaußenzahnkranzes in the teeth of the inner ¬ ring gear and is firmly connected to a in the direction of rotation of the Taumelaußenzahnkranzes extending ferromagnetic ring, with at least two pole shoes which project through independently energizable coils to the inner circumferential surface of the ferromagnetic ring and are distributed with radial play to the ring on its circumference.
Durch den Antrieb der Achse mittels eines Taumelzahnkranzes oder Taumelaußenzahnkranzes ist mit wenigen einfachen Bauteilen eine hohe Getriebeübersetzung möglich, die zu einer gleichförmigen Zeigerbewegung führt . By driving the axle by means of a wobble gear ring or Taumelaußenzahnkranzes a high gear ratio is possible with a few simple components, which leads to a uniform pointer movement.
Sind Taumelzahnkranz oder Taumelaußenzahnkranz einteilig mit dem ferromagnetischen Ring ausgebildet, so führt dies zu einer kostengünstigen Reduzierung der Bauteile und einer Montage¬ vereinfachung . Are wobble ring gear or Taumelaußenzahnkranz formed integrally with the ferromagnetic ring, this leads to a cost-effective reduction of components and assembly ¬ simplification.
Eine weitere Bauteilreduzierung und Reduzierung des Montage¬ aufwandes wird dadurch erreicht, dass die Spulen auf eine Leiterplatte aufgebrachte Planarspulen sind, die Durchführ¬ öffnungen in der Leiterplatte umschließen, durch die die Pol¬ schuhe hindurchragen. Dies reduziert auch die Baugröße der Anzeigeeinrichtung. Dabei ist die die Spulen tragende Leiter¬ platte gleichzeitig ein integraler Bestandteil des Messwerks. Je nach den vorhandenen Platzverhältnissen können das Zahnrad und der Taumelradkrant oder der Innenzahnkranz und der Taumelaußen¬ zahnkranz Stirnzahnräder oder Kegelzahnräder sein. A further reduction in components and reduction of assembling ¬ loss is achieved in that the coils are applied planar coils on a printed circuit board, the lead-through openings ¬ enclose in the circuit board through which project beyond the pole shoes ¬. This also reduces the size of the display device. The board carrying the coils ¬ plate is simultaneously an integral part of the measuring element. Depending on the available space, the gear and the Taumelradkrant or the inner ring gear and the Taumelau ¬ gear ring be spur gears or bevel gears.
Zu einer die Anzahl der Bauteile und damit auch den Montageaufwand verringernden Ausbildung führt es, wenn die Polschuhe mit einer Polplatte verbunden sind, die sich annähernd rechtwinklig zu den Polschuhen erstreckt wobei Polschuhe und Polplatte einteilig ausgebildet sein können. It leads to a number of components and thus also the assembly cost reducing training, when the pole pieces are connected to a pole plate which extends approximately at right angles to the pole pieces, wherein pole shoes and pole plate can be integrally formed.
Je nach Platzverhältnissen können die Polschuhe sich zumindest annähernd rechtwinklig zur Zahneingriffsrichtung von Taumel¬ zahnkranz bzw. Taumelaußenzahnkranz in das Zahnrad bzw. das Innenzahnkranz oder sich zumindest annähernd gleichgerichtet zur Zahneingriffsrichtung von Taumelzahnkranz bzw. Taumelaußenzahn¬ kranz in das Zahnrad bzw. das Innenzahnkranz erstrecken. Depending on the space conditions, the pole pieces can extend at least approximately perpendicular to the meshing direction of the swash ¬ sprocket or wobbling external gear in the gear or the ring gear or at least approximately same direction as the tooth direction of engagement of the swash gear rim or swash outer teeth ¬ wreath in the gear or the internal gear.
Zur einfachen Sicherstellung des Eingriffs des Taumelzahnkranzes oder des Taumelaußenzahnkranzes in die Zähne des Zahnrads kann der Taumelzahnkranz bzw. der Taumelaußenzahnkranz über ein oder mehrere elastische Elemente auf seiner der Eingriffsseite der Verzahnung des Taumelzahnkranzes in die Zähne des Zahnrads abgewandten Seite abgestützt sein. In order to easily secure the engagement of the wobble ring gear or the wobble outer ring gear in the teeth of the gear, the wobble gear ring or the wobble outer ring gear can be supported on its side facing away from the engagement side of the teeth of the wobble gear ring in the teeth of the gear wheel via one or more elastic elements.
Dabei kann der Taumelzahnkranz bzw. der Taumelaußenzahnkranz über den ferromagnetischen Ring an den elastischen Elementen in Anlage sein. In this case, the wobble gear or the Taumelaußenzahnkranz be on the ferromagnetic ring on the elastic elements in Appendix.
Um eine hohe Robustheit gegenüber Montageeinflüssen zu erreichen kann das Messwerk aus Zahnrad, Achse, Taumelzahnkranz, ferro- magnetischem Ring und elastischen Elementen in einem Gehäuse angeordnet, insbesondere das Messwerk von dem Gehäuse gekapselt sein . In order to achieve a high degree of robustness against assembly influences, the measuring mechanism comprising gear wheel, axle, wobble ring, ferromagnetic ring and elastic elements can be arranged in a housing, in particular the measuring mechanism can be encapsulated by the housing.
Zur Trennung der Polschuhe von dem Inneren des Gehäuses kann dabei der Boden die in das Gehäuseinnere ragenden Polschuhe aufnehmende Taschen aufweisen. Zu einem raumsparenden, kompakten Aufbau führt es dabei, wenn an der dem Inneren des Gehäuses abgewandten Seite des Bodens die Leiterplatte in Anlage ist, wobei vorzugsweise auf der dem Gehäuse abgewandten Seite der Leiterplatte die Polplatte an¬ geordnet sein kann. In order to separate the pole pieces from the interior of the housing, the bottom may have the pockets receiving the pole pieces projecting into the interior of the housing. To a space-saving, compact design leads to it, if on the side facing away from the interior of the housing side of the floor, the circuit board is in contact, preferably on the side facing away from the housing of the circuit board, the pole plate can be arranged on ¬ .
Zum mechanischen Schutz sind vorzugsweise Leiterplatte und/oder Polplatte ganz oder teilweise mit einer Kunststoffumspritzung versehen . For mechanical protection preferably printed circuit board and / or pole plate are wholly or partially provided with a plastic extrusion.

In the embodiment of Figure 2 are gear 2 and Taumelradkranz 3 spur gears, the wobble toothed ring 3, the ferromagnetic ring 4 and the elastic elements 5 are arranged radially to the gear 2 and attached as a connected ¬ partial group radially to the pockets 7 of the bottom 6 ,
Bis auf die Ausbildung von Zahnrad 2 und Taumelradkranz 3 als Kegelzahnräder entspricht der Aufbau der Figuren 3 und 4 der Figur 2, wobei in Figur 3 die Zähne des Zahnrads 2 schräg von dem Boden 6 weg und in Figur 4 schräg zum Boden 6 hin gerichtet sind. Except for the formation of gearwheel 2 and wobble gear rim 3 as bevel gears corresponds to the structure of Figures 3 and 4 of Figure 2, wherein in Figure 3, the teeth of the gear 2 are directed obliquely away from the bottom 6 and in Figure 4 obliquely to the bottom 6 out ,
In den Figuren 5 und 6 entsprechen die Zahnräder 2 und Tau¬ melradkränze 3 denen der Figuren 3 und 4. In the figures 5 and 6, the gears 2 and Tau ¬ melradkränze 3 correspond to those of Figures 3 and 4.
Die Taumelzahnkränze 3 sind aber axial zur Achse 1 über den ferromagnetischen Ring 4 und die elastischen Elemente 5 mit der freien Stirnseite der Taschen 7 des Bodens 6 verbunden. In Figur 7 sind Zahnrad 2 und Taumelzahnkranz 3 entsprechend Figur 4 als Kegelräder ausgebildet. Entsprechend deren Kegelneigung ist der Taumelzahnkranz 3 über den ferromagnetischen Ring 4 und die elastischen Elemente 5 mit den Taschen 7 des Bodens 6 verbunden . However, the wobble ratchets 3 are connected axially to the axis 1 via the ferromagnetic ring 4 and the elastic elements 5 with the free end side of the pockets 7 of the bottom 6. In FIG. 7, toothed wheel 2 and wobble toothed ring 3 are formed as bevel gears according to FIG. According to their conical inclination of the wobble gear 3 is connected via the ferromagnetic ring 4 and the elastic elements 5 with the pockets 7 of the bottom 6.
Wie in Figur 8 zu sehen ist, sind auf der Leiterplatte 10 die Planarspulen 11 über einen Halbkreis 20 gleichmäßig verteilt angeordnet und werden von den Polschuhen 8 durchragt. Von einer nicht dargestellten Steuereinheit werden die Planarspulen 11 derart unterschiedlich bestromt, dass an den Polschuhen 8 entsprechend unterschiedliche Magnetfelder auf den ferromag- netischen Ring 4 wirken und diesen entsprechend unterschiedlich gegen die Kraft der elastischen Elemente 5 aus seiner darge¬ stellten Neutrallage auslenken. Entsprechend wird auch der Taumelzahnkranz 3 ausgelenkt. In der Nullage der Achse 1 ist die am linken Ende des Halbkreises 20 befindliche Planarspule 11 mit dem stärksten Strom und die am rechten Ende des Halbkreises 20 befindliche Planarspule 11, Λ mit dem schwächsten Strom sowie die mittlere Planarspule 11 x mit einem mittleren Strom beaufschlagt. As can be seen in FIG. 8, the planar coils 11 are distributed uniformly over a semicircle 20 on the printed circuit board 10 and are penetrated by the pole shoes 8. From a control unit, not shown, the planar coils 11 are energized differently in such a way that act on the pole pieces 8 correspondingly different magnetic fields on the ferromagnetic ring 4 and deflect this correspondingly different against the force of the elastic elements 5 from his Darge ¬ set neutral position. Accordingly, the wobble gear 3 is deflected. In the zero position of the axis 1 located at the left end of the semicircle 20 planar coil 11 with the strongest current and the right end of the semicircle 20 located planar coil 11 , beauf with the weakest current and the mean planar coil 11 x is acted upon by a medium current.
Wird nun die Strombeaufschlagung der linken Planarspule 11 im gleichen Maß erhöht wie die der rechten Planarspule 11, Λ ver¬ ringert wird, so ändern sich auch entsprechend deren Magnet- felder, was zu einer Taumelbewegung des ferromagnetischen Rings 4 und mit ihm des Taumelzahnkranzes 3 entlang des Halbkreises 20 führt. Dadurch wird von dem Taumel Zahnkranz 3 das Zahnrad 2 zu einer Drehbewegung angetrieben, die über die ebenfalls drehende Achse 1 auf eine nicht dargestellte Zeigerachse übertragen wird. Der auf der Zeigerachse angeordnete Zeiger bewegt sich dann entsprechend entlang einer ebenfalls nicht dargestellten bo¬ genförmigen Skala. If now the current to the left planar coil 11 to the same extent increased as that of the right planar coil 11, Λ ver ¬ is Ringert, so what along a wobbling motion of the ferromagnetic ring 4 and with it the wobble ring gear 3 also change according to their magnetic fields of the semicircle 20 leads. As a result, the gear 2 is driven by the wobble sprocket 3 to a rotational movement, which is transmitted via the likewise rotating axis 1 to a pointer axis, not shown. The pointer arranged on the pointer axis then moves along a bo ¬ genförmigen scale, also not shown.
